NITE STAT IMPROVEMENT IN GAS"MACHINES.

Specification forming part of Letters Patent No. 115,592, dated June 6,1871.

I, Tnoims B. Foennrv, of the county of Kings and State of New York, haveinvented a certain Improvement in Gas-Machines, of which the followingis a specification:

a-tare and Objects of the Invention.

My invention relates to those gas-machines in which the gas or vapor isgenerated from hydrocarbon liquid contained in aretort heated by theexternal application of heat derived from the combustion of part of thegas manufactured in the machine itself and its object is to facilitatethe heating of the retort when the machine is first started.

In some machines of the above class it is customary to burn some alcoholunder the retort until it has acquired heat sufficient to generate vaporor gas, after which the combustion of a portion of the gas in a suitableburner furnishes all the heat required. In others, vapor-burners areattached to the machine, and, by means of it, get the retort up to aworking heat; while in others gas is manufactured for the purpose ofheating the retort by raising a gas-holder, provided with suitablevalves and ducts, so that when the holder is raised air is drawn into itthrough a chamber containing gasoline.

My invention consists in the arrangement of pipes leading from a tankcontaining hydrocarbon liquid, and into which compressed air is forcedto the burner, heating the retort, and to the gas-holder, so that thevapors can be conducted from the tank of hydrocarbon and compressed airto the burner for heating the retort and the gas-holder; or, from thegasholder to the retort burner, it being first filled either to eachsingly, or to both, either with or without the induction of anadditional portion of air, as may be desired.

In the drawing, Figure 1 shows a gas -ma chine containing myimprovements- A being the retort, which is shown in section 5 B, theburner; O, the gasholder tank;

and E is a tank containing some gasoline, at, and a quantity ofcompressed air, I). F is the pipe through which gasoline or otherhydrocarbon liqnid is forced into the retort by the expansive force ofthe volume of compressed air, I), acting on its surface. H is anair-pipe, one branch of which leads to a pump or other apparatussuitable for compressing it. The other branch, 62, of this pipe Hcommunicates with the inlet-pipe I, to the holder, and the gas-pipe Jleading to the burner K, or with either of them; and this pipe (1 Ifurnish with a suitable valve or cook, f, by means of whichcommunication between the inlet-pipe I or burner-pipe J, or both of themand the tank E can be cut off whenever the retort has become hot enoughto make gas to heat itself.

Figs. 2 and 3 show the pipes I and d in section. Fig. 3 shows the pipe61 joined directly to I, so that the superoarbureted air in the tankwill be conveyed directly to the holder or the burner Kwithout anyfurther admission of air, or rather, it should be said, admixture. Fig.3 shows an air-induction apparatus placed between the pipes I and d forthe purpose of inducin g an additional volume of air.

Claims.

'bination with the pipes H, d, J, and I, substantially as set forth.

2. The subject-matter of the first claim, in combination with agasmachine, consisting of a retort, A, gas-holder D, and gas-holder tank0, substantially as set forth.
